I did here that if enough use it then it'll stop showing.
My game demo (https://jeffweber.itch.io/just-flip-demo) has over 500 DL's and it still happens. Problem is a lot of people probably aren't playing it because they get this warning.
I understand I can get it digitally assigned but from what I understand it's not easy and not cheap. Unless there is an indie friendly way of doing it.
